Draw.io - System Architecture Diagram design

I am looking for a skilled individual to design a system architecture diagram using Draw.io. The purpose of the diagram is to communicate the system to stakeholders, so it should be clear and easy to understand. I require a mix of both high-level and detailed components to be included in the diagram. For visual style and notation, I prefer Business Process Model and Notation (BPMN). Ideal candidates should have experience in system architecture design and a strong understanding of BPMN. I have a very rough sketch of the applications, databases, and other objects that need to be redrawn and redesign and documented.
